Smallpox can evolve rapidly despite low mutation rates
Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Poxviruses, a group of DNA-containing viruses that includes smallpox, are responsible for a wide range of diseases in humans and animals. They are highly virulent and able to cross species barriers, yet how they do so has been largely a mystery because of their low mutation rates. While smallpox was considered officially eradicated by the World Health Organization in 1980, concerns about its use as a bioterrorism agent – and the finding that other poxviruses, such as monkeypox, can be transmitted from animals to humans – have spurred renewed interest in understanding how they replicate.

Far more could be done to stop the deadly bacteria C. diff
USA Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
VideoBriefJust days after doctors successfully removed a tumor from Bailey Quishenberry's brain, the 14-year-old was spiraling downhill, delirious and writhing in pain from an entirely new menace. Her abdomen swollen 10 times its normal size and her fever skyrocketing, Bailey began wishing she could die, just to escape the agony. Bailey had contracted a potentially fatal infection called Clostridium difficile, or C. diff, that ravages the intestines. More

Fluoroquinolones tied to higher risk of serious arrhythmias
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Fluoroquinolones, especially gatifloxacin, moxifloxacin and ciprofloxacin, are associated with significantly increased risks of serious arrhythmias, according to a new study. The link has been suspected before, but little data exist to support it, researchers write in a report online in Clinical Infectious Diseases. More



Infections among homeless could fuel wider epidemics
Reuters via Fox News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Homeless people across the world have dramatically higher rates of infection with tuberculosis, HIV and hepatitis C and could fuel community epidemics that cost governments dearly, a study showed. With an estimated 650,000 homeless people in the United States and around 380,000 in Britain, experts said high levels of infection would not only cause yet more poverty and distress for those without homes, but could also become a wider problem.

Gene deletion drives more than a quarter of breast cancers
Medical Xpress    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A new study shows that the lack of a certain gene occurs in almost 28 percent of human breast cancers, playing a role in some 60,000 breast cancer cases in the United States and 383,000 worldwide this year. Recent studies have observed loss of the gene NF1 in glioblastoma (an aggressive brain cancer), lung and ovarian cancers, but the significance has been overlooked because it was thought that two copies of the gene (one from each parent) needed to be missing to cause cancer.

Corticosteroids disappoint in dengue fever
Reuters via Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A short course of oral corticosteroids given early in dengue fever did not improve outcomes or delay complications, a new study from Vietnam found. Researchers had speculated the drugs might be helpful given that complications of the disease such as dengue shock syndrome and hemorrhagic fever are thought to be mediated by the immune system.

Harvard cracks DNA storage, crams 700 terabytes of data into single gram
Extreme Tech    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A bioengineer and geneticist at Harvard's Wyss Institute have successfully stored 5.5 petabits of data – around 700 terabytes – in a single gram of DNA, smashing the previous DNA data density record by a thousand times. The work, carried out by George Church and Sri Kosuri, basically treats DNA as just another digital storage device. Instead of binary data being encoded as magnetic regions on a hard drive platter, strands of DNA that store 96 bits are synthesized, with each of the bases (TGAC) representing a binary value (T and G = 1, A and C = 0).

Staph-infected renal patients getting inferior treatment?
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Physicians in the United States may be too quick to prescribe vancomycin for patients receiving hemodialysis who develop methicillin-susceptible Staphylococcus aureus bloodstream infections. Cefazolin might be a better choice, according to results from a new study published online in the Journal of the American Society of Nephrology. Kevin E. Chan, M.D., from the Clinical Research Division, Fresenius Medical Care North America, and the Nephrology Division of Massachusetts General Hospital, Boston, and colleagues studied the trends in antibiotic use among MSSA-infected patients receiving hemodialysis.

Hospital tech's arrest sets off hepatitis scare in 8 states, shows flaws in the system
Fox News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
VideoBriefRadiology technician David Kwiatkowski was a few weeks into a temporary job at the University of Pittsburgh Medical Center-Presbyterian in 2008 when a co-worker accused him of lifting a syringe containing an addictive painkiller from an operating room and sticking it down his pants. In what may be the scariest part of all, authorities say that when he swiped the fentanyl syringe, he left another one in its place, filled with a dummy fluid, ready to be used on a patient. But Kwiatkowski did not go to jail. No one in Pittsburgh even called the police. More

To diagnose illness in areas of the body that are hard-to-reach, clinicians increasingly use tiny space-age probes, which can see inside single living cells. A new study published in the journal Digestive Diseases and Sciences reveals that specialists who are beginning to use these devices may be interpreting what they see in different ways. More



Why whooping cough is back
MyHealthDaily via Fox News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The number of whooping cough cases in the U.S. this year is on track to be the highest in 50 years, although one researcher says the main reason behind the disease's apparent resurgence is a heightened awareness of it. Besides improved reporting of cases of whooping cough (which is also called pertussis), factors in the disease's resurgence include the fact that vaccines don't completely protect against it, and that the current vaccine provides even less protection than previous ones did, according to Dr. James Cherry, a professor of pediatric infectious diseases at the David Geffen School of Medicine, UCLA.

Should young men be vaccinated against human papillomavirus?
Medical News Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article

Yosemite tourist dies after contracting hantavirus
The Associated Press via USA Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A popular lodging area in Yosemite National Park could be linked to a rare rodent-borne disease that has killed a California tourist who stayed there this summer, officials said. A man who stayed at Curry Village in June died after contracting hantavirus pulmonary syndrome. A woman who also stayed in a canvas tent cabin about 100 feet from him on overlapping days has become seriously ill, officials at the California park said. The virus was found in the feces of deer mice in the family friendly lodging area of cabins, according to tests by the Centers for Disease Control and state health officials. More
